I hear your question loud and clear. I have been thinking about the fact that I don't understand why Jesus didn't just speak plainly. Yes, he spoke in parables so the common man would understand - didn't God know that we wouldn't understand? Why wasn't the Bible written like the book "life's little instruction book"?
There should simply be no room for misunderstanding or interpreting things in a different way. We shouldn't be able to fight over the translation of specific words or their tense. It gets ridiculous at times.
The law code was cumbersome and just too plain much but it did provide God's specific instructions for everyday situations.
My conclusion, to myself of course, is that since God didn't make the NT as clear as the law code; he intended it that way. I won't let anyone's interpretation of the Bible come between me and loving Christ. I will love Christ and strive to be a morally upright person (what is that you say? Hmmm...I guess it means not doing anything that will get me thrown into jail or divorced - hahahahahaha).
One day I hope it will all come clear - if not, I'll die a satisfied person anyway.
